DEAD FLAT Vacuum conveyor #5

Inspection also makes use of dead flat surface.
Vacuum conveyor keeps the same distance between measuring tools and objects on a belt by its flat surface.  Laser-type measuring machines and camera needs precise clearance from objects to capture their real figure.  Substrates, wafers, flat sheets, etc are inspected precisely and  continuously.
The picture below measures vertical fluctuations of the belt by laser.

Printing can be done on paper, plastic sheets and films, cloth, non-woven fabric, glass, ceramic sheets and others.

The picture below conveys paper envelops.  Vacuum conveyor is inclined.
It is not set parallel to the ground.  But this conveyor keeps envelops on the belt.

DEAD FLAT Vacuum conveyor #3

Then what can be done on a DEAD FLAT vacuum conveyor?
It is printing.
Screen printing is now widely used in many process, such as writing circuits on print circuit boards and locating electrodes on solar cells with conductive silver paste.

DEAD FLAT Vacuum conveyor #2

What about tracking?
Our vacuum conveyor is equipped with Edge Positioning Control Unit.
This unit controls belt tracking within a few milimeters.
When this conveyor runs for 8 hours a day,
horizontal belt fluctuations is within a few milimeters.

This belt runs straight, because the driven pulley shaft is controlled by Edge Positioning Control Unit.

DEAD FLAT Vacuum conveyor #1

Mountain peaks are beautiful.  

Calm water in a lake settles our mind. 

Printing is done on paper, plastic films, ceramic plate, rubber, and cloth,

only if they are placed flat.  

How can we make them flat?

In addition to gravity, they become flat by vacuum.

The picture below is measurement by laser

on vertical movement of vacuum steel belt surface.

It is controlled within 50 microns.

On Steel Belt No.18 Suction and vacuum conveyance by perforated belts

The last one, very popular perforation is as below:

Suction and vacuum holes are all over the belt.
This works to hold very small parts and very thin objects like paper, plastic sheet and metal sheet.  Flat surface can be realized by suction and vacuum.

Similar pattern is as below.

Locations of these blue parts or cases do not move beyond standing plates.
